Cryotherapy, or “cold therapy,” has become a buzzword in the wellness and biohacking world. While it’s traditionally been used to reduce pain, inflammation, and speed up recovery for athletes, some people are now exploring whether it can also assist with weight loss. In this article, we’ll look at the science behind cryotherapy, examine its potential for helping with weight loss, and address common questions and misconceptions.
What is Cryotherapy?
Cryotherapy involves exposing the body to extremely cold temperatures for short periods. There are several types of cryotherapy:
- Whole-Body Cryotherapy (WBC): You enter a chamber cooled to temperatures as low as -160°C (-256°F) for about 2-4 minutes.
- Localised Cryotherapy: Cold is applied to specific areas, such as a sore muscle, using devices like cold packs or sprays.
- Ice Baths: A simpler, at-home version where the body is immersed in cold water to aid muscle recovery.
Each of these methods aims to reduce inflammation, relieve pain, and boost physical recovery, but they have also been linked to potential weight loss benefits.
How Might Cryotherapy Support Weight Loss?
Several claims connect cryotherapy to weight loss, with the main ideas centering on how cold exposure affects the body:
1. Increases Calorie Burn: When exposed to intense cold, the body has to work harder to maintain its core temperature, leading to increased calorie burn.
2. Boosts Metabolic Rate: Some research suggests that regular cryotherapy sessions may raise your metabolism, meaning you may burn more calories even at rest.
3. Activates Brown Fat: Unlike white fat, which stores energy, brown fat burns energy to produce heat. Cold exposure can activate brown fat, potentially helping with fat loss.
4. Enhances Workout Recovery: By reducing soreness, cryotherapy may support quicker recovery, allowing you to maintain an active lifestyle, which indirectly supports weight management.
What Does Research Say?
While cryotherapy is linked to some intriguing benefits, scientific evidence specifically on cryotherapy and weight loss remains limited. Here’s what we know from available research:
- Caloric Burn from Cold Exposure: The process of rewarming the body does lead to additional calorie burn, but it’s temporary, usually lasting only a few hours after a cryotherapy session. Estimates vary, but it’s generally modest and not significant enough to replace diet or exercise.
- Activation of Brown Fat: Studies have shown that cold exposure can activate brown fat, which burns calories to keep the body warm. However, it’s unclear if the short bursts of exposure in cryotherapy chambers are sufficient for sustained fat burning. Research is ongoing to determine the full effect of brown fat activation on weight loss.
- Boost in Metabolic Rate: There is some evidence that cold exposure can increase the body’s metabolic rate, leading to more calories burned at rest. But the effect may not be enough to produce significant weight loss on its own and often requires consistent sessions.
Can Cryotherapy Alone Lead to Weight Loss?
While cryotherapy has potential, it’s not a magic solution for weight loss. Here’s why:
- Temporary Calorie Burn: Although cryotherapy burns calories, the effect is short-lived, and the calories burned may not be enough to cause noticeable weight loss on their own.
- Not a Substitute for Exercise and Diet: Cryotherapy can’t replace a balanced diet and regular exercise, which are essential for long-term weight management.
- Supportive Rather Than Primary: Cryotherapy may support weight loss by enhancing muscle recovery, reducing soreness, and improving energy levels, which can help you stay active and maintain an exercise routine.
How to Incorporate Cryotherapy into a Weight Loss Plan
If you’re interested in cryotherapy as a way to support your weight loss goals, here are some tips to make the most of it:
- Combine with Exercise: Cryotherapy is best used as a recovery tool alongside regular physical activity.
- Maintain a Healthy Diet: Diet is the cornerstone of any successful weight loss plan. Cryotherapy can complement but not replace dietary changes.
- Stay Consistent: Regular sessions may provide the best results, but remember that cryotherapy alone won’t be enough for weight loss.
- Listen to Your Body: Not everyone responds the same way to cold therapy. Some people may feel great after a session, while others may find it too intense. Adjust based on your comfort and consult a health professional if necessary.
Final Thoughts
Cryotherapy may offer some weight loss benefits, especially when used in conjunction with a healthy diet and regular exercise. While the extra calories burned and potential brown fat activation are appealing, cryotherapy’s primary benefits lie in its recovery and wellness effects. Cryotherapy should be seen as a supportive tool in a holistic approach to weight management, rather than a standalone solution.
